Title: Improvements in or relating to stoker driving mechanism
IPC: F23H11/20
Filed: 1923-03-07
Abstract: 216,943. Babcock & Wilcox, Ltd., and Hollick, F. W. March 7, 1923. Grates.-In stoker driving-mechanism there is included in the transmission train e between the grate driving shaft a and the actuator j thereof; an epicyclic gear with provision for interrupting at predetermined times the application of a brake. When the brake-wheel h<1> rotates freely, no movement is transmitted to the rest of the gearing, but when the brake h is applied to resist rotation of the brake-wheel, movement is transmitted through the spur gearing e to the, shaft a. The speed of the grate is varied by releasing and applying intermittently the brake h either by means such as a solenoid or by cams. The solenoid k shown in Fig. 8 is controlled by a switch brush l rotated at low speed past an annular series of contacts m adapted to be switched into or out of circuit. When there is no current in any of the contacts, the solenoid core falls, thereby operating the lever k<1> pivoted at k<2>, the lever k<3>, the bell crank lever k<4> and consequently causing the application of the brake shoes h. To reduce the speed of the grate current is switched on to one or more contacts according to the speed desired. The brake is controlled mechanically by means of a set of cams n as shown in Fig. 5. The cams are rotated at a low constant speed and are adapted to engage the brake-lever selectively, the arrangement being such that for maximum grate speed the cams are so positioned that the brake is not released and for reduction of speed the cams are positioned to release the brake for predetermined intervals. The adjustment of the cams is provided by means of a lever which when moved axially causes longitudinal movement of the cams and also effects corresponding movement of an eccentric sleeve t which temporarily lifts the brake lever. A driving-motor operatively connected to the transmission train is mounted in the gear case b.

Title: Improvements in or relating to character recognition apparatus
IPC: G06V10/24
Filed: 1965-02-17
Abstract: 1,030,835. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 17, 1965 [Feb. 18, 1964], No. 6749/65. Heading G4R. In a character reader a line of characters is scanned in a series of vertical strokes and signals representing the upper and lower portions of the character are used to compensate for vertical displacement of the character and for size of character. Most characters, such as ((a," " c," " e," have no ascending portions (such as have " b," " d " &c.) or descending portions (" g," " f," " q " &c.). When a line of characters is scanned the height distribution of the video signals is as shown in Fig. 2, the bulk of signals being in the middle range. Ascending and descending portions produce parts 23 and 25 of the curve. To track the height of the characters, reference pulses are produced which, ideally, correspond to the sections 23, 21 and 25. These pulses (Fig. 6, not shown) consist of a short high-amplitude positive pulse for each of sections 23, 25 and a long low-amplitude negative pulse filling the period between the first two and corresponding to part 21 of the curve. Each of the three pulses is applied to a gate, 45, 47, 49, Fig. 5 (not shown), enabled by the video signal, so that if the character has been cut by the scan at the instant of occurrence of the pulse, the pulse is passed by the gate. A top summing integrator 51 receives the top positive pulse and the middle negative pulse. A bottom summing integrator 53 receives the bottom positive pulse and the middle negative pulse. The outputs from the integrators are compared continuously at 55 to provide a control signal for the vertical sweep position and the integrator outputs are summed at 57 to provide control signals for the vertical sweep speed, to maintain the time taken to cross the character with a scanning stroke constant whatever the size of the character. The horizontal scanning speed is also controlled to maintain constant the total scan time for a character.

Filed: 1926-03-12
Abstract: 249,149. Bliss Co., E. W., (Assignees of Kruse, P.). March 13, 1925, [Convention date]. Hollow-ware.-In a machine for making lap seam bodies of cans, zinc cells for dry batteries, &c. of the kind in which sheet metal blanks with perliminarily bent edge portions for forming the seam are curved in turn by jaws over one of a series of intermittently traversed formers and are soldered thereon and subsequently ejected therefrom, means are provided to effect a preliminary curve approximately to the shape of the former on portions of the blank extending from the seam portions for a distance towards the centre of the blank, e.g. for # to “ of the circumference of the body, so that when the blank is finally wrapped round the former these portions will conform to the shape thereof. For cases in which blanks of resilient metals are used this curve may be of smaller radius than that of the former so that in the wrapping operation they are flattened to conform to the shape of the former. The edges y, y<1>, Fig. 10, for forming the seam may be first preliminarily bent to the shape of the former or to a smaller radius and the parts z, z<1> then similarly curved to the same or a different radius from the parts y, y<1> or both may be simultane. ously effected to the same radius by pairs of rolls. The former may be circular, elliptical, &c. Blanks x are fed from a magazine W<2> by pawls 11 on bars 10 which are reciprocated by link 13, lever 14, connecting-rod 15 from a shaft geared to the main shaft 19. The blanks first pass between a pair of dies Y, Y<1> for stamping letters or inscriptions thereon. the die Y' being operated by an eccentric 53. They then pass between idle or driven rolls T and cam shoes T<1> for curving the edges thereof and then pass into position between a fixed die V, Fig. 4, and a pair of eccentrically operated dies W for bending the parts z, z'. The blanks pass along guides and are engaged in the space between one of the formers F and pivoted bending-jaws G, G<1>, which are carried by the links a of an intermittently driven chain D. The edges of the blank pass along acid or solder supplying rolls 55. Rollers k on the jaws at this stage run on inclined tracks H, H<1> on the bed so as to tilt the jaws to bend the blank round the former F, one of the rollers being slightly in advance of the other so as to effect the beading of one side first. The blanks then pass under a soldering-iron m and in a further stage the jaws drop out of position and subsequently the bodies are removed from the formers by ejectors U carried by rods 25, which are reciprocated by lever mechanism from a cam or a longitudinal shaft driven from the shaft 19. Each jaw may consist of a bending-member 60, Fig. 8, and an actuating member 61, both mounted on the same pivot e and resiliently connected to each other by a spring 62 surrounding a stud 63 secured to the part 61 and provided with a stop nut 64. A blade 66 engages the blank near the seam.
Patent GB-432176-A (GB)
Title: Improvements in and relating to the recovery of volatile liquids
IPC: B01D53/00
Filed: 1935-03-05
Abstract: In the recovery of solvent vapour from solutions employed in an installation for the making of films, foils, coated papers, &c., fire risk is reduced by indirectly cooling the vapour in a condenser 4 with solid carbon dioxide contained in a receptacle 5 around which the vapour is circulated, the gaseous carbon dioxide evolved being recirculated from a gas holder 12 by a fan 15 to the vapour collecting space 2 of the installation.  The condensed solvent vapour collects at the base of the condenser, and the vapour-free, carbon dioxide containing, air circulates to the collecting space 2 through a duct 7, the <PICT:0432176/III/1> vapour-laden air flowing back to the condenser through a duct 8 to continue the cycle of operations. In a modification, slower gasification of the solid carbon dioxide is achieved, by arranging the receptacle 5 outside the condenser 4, a pipe coil surrounding a block of the carbon dioxide communicating with a similar coil in the condenser, the coil being empty or filled with methyl chloride to form a supplementary refrigerant.  A pump may be inserted in the pipe line 11 between the receptacle 5 and the gas holder to create pressure in the latter; in this modification the gas holder may be dispensed with.  The quantity of carbon dioxide admitted to the system may be controlled by a meter 28 and the temperature in the condenser regulated by an electrical thermometer.
